Okay, not only are the disabled cores (and their local caches) sometimes tested to fail, sometimes they are NOT TESTED AT ALL. If the production run says we're only going to have 3 out of 4 possible cores (with cache), they're not going to bother testing the fourth core (and its cache) if the first three test successfully. Worse, if they're calling for 2 cores out of 4, they test and get two good ones and DO NOT TEST the third and fourth core.
Remember, also, this is not just the core that is tested but the L2 cache. In multiprocessing, a core is hardly useful without a working local cache.
Many of these re-enabled cores have faulty caches. The benchmarks do not show any benefit and in many applications that extra core without cache actually degrades peformance.
Thanks for your post. I thought it laughingly idiotic to assume that so many of these devices have hard drives in them to begin with. I guess it wouldn't have made the local public-interest story on so many radio stations this morning if they didn't say that.
They aren't really finding files. The files, of course, are marked for deletion and are deleted with the data left behind in unallocated sectors. What they're doing is using forensic tools to take this raw data off the hard drive and re-assemble it into files, something well-known about computers. The point of the story is that nobody knows it's true about many digital copiers, too.
As for the $500 device to wipe the drive, this device is expensive because it's a little computer that does a "wipe" of the hard drive data to FIPS 142-2 and NIST 800-88 4 standards.
For practical purposes I think the copiers should wipe free space on the hard drives on a regular basis, but this would likely result in premature drive failure in the field.
I really liked OS/2's Workplace Shell but for one nagging problem that you wouldn't think was a problem until you experienced it first-hand. The WS remembers every window's size and position. Not some, but *all* of them, even if they were just regular applications like, say, the file manager. What do you think happens when you reduce screen resolution because of, say, a new graphics card, and you try to right-click "Properties" to adjust the resolution? It's off the right-hand side of the screen.
Worse, this little cache of window dimensions would corrupt, and you'd be presented with 1x1 pixel windows for everything.
I'm not sure if this was ever fixed in OS/2 Warp Connect.
Another favorite is floating your mouse pointer from WS to Windows sub-window and then back to WS: it hangs my computer.
We've ascended the journalistic ladder from daily newspaper human interest filler to a monthly magazine, but we notice that the PopSci article is dated 03-04-2010.
The infamous smart cards used by cell phones and governments do this but in a smaller scale. After several failed attempts to use your PIN the secrets (keys, certs, data) on the card are erased. Actually, a circuit physically burns out the memory and permanently disables it. The card must be replaced with a new one at your local smart card processing office.
Let's see, we are reading a generically syndicated human interest filler story from Santa Fe, New Mexico that was published in the Chicago Tribune two days ago.
This isn't the New York Times. It's pure silliness used to fill white space in newsprint as our other posters have agreed.
Just download the SCO OpenServer trial download. It reads Xenix filesystems with no problem. After all, SCO Unix is Xenix. Be careful, because I'm not talking about SCO Unixware, but the older software called SCO OpenServer. That's the new name for Xenix-based SCO Unix. This from an old-time Xenix on-site service guy.
I always enjoyed the GNU Hello World packages in C and C++. They seem too large for their purpose, but I supposed they were trying to test something under the surface.
Are the Richard Nixon tapes online yet? Last I bothered, they were $6 per audio cassette. C-Span Radio would play them every week as they were released several years ago. It was my yard work companion for two years.
Which is more efficient: induction charging, like old Chevrolets, or direct dry contact charging? From what I remember of my induction charging toothbrush it was safe but sure got hot to the touch.
The add-on DLC for, say Guitar Hero, is both free and costs money. What difference does it make if the data to implement the DLC is on the disc or downloaded from a remote server? The money is being used to pay to license the software. As all users of software should know, mere physical possession of software means nothing. It is licensed to you, whether for no charge (free) or for a fee.
It still does not matter. The customer is the US Government. They want contractors to abide by certain rules including security clearance vetting. These do not involve sexual orientation but they do involve blackmail risks which is perfectly reasonable for them to be concerned about.
If you do not agree with security clearances you should not work for entities that require them. They really do not care about sexual orientation. They only care about exploitation risks. It really is that simple. The question is: can you be extorted? It's a valid question. It needs to be addressed.
By turning off the password checking the system stops consuming time hacking passwords. Plus, you can't brute-force guess a certificate. The problem literally goes away.
I'm sorry, but using passwords is completely wrong. The only real answer is to disable password authentication and only allow certificates. It's completely easy for anyone with access to a text editor. Ask your sysadmin to do this: PubkeyAuthentication yes PasswordAuthentication no PermitEmptyPasswords no ChallengeResponseAuthentication no
Your problem goes away completely.
If you think ssh certificates are hard to use then maybe web hosting is not the right business for you to be in.

Okay, that settles it. I'm changing my Amazon Payphrase to "Sublime Arrogance."
Yeah, I get it. The guy in PopSci seems more plausible but I really hope that people take PopSci for what it is, popular science.

Thing is, Red Hat and friends stopped waiting and already moved to NSS over three years ago. http://en.wikipedia.org/wiki/Network_Security_Services

The Slingcatcher from http://www.slingbox.com/go/slingcatcher is pretty good at doing this.
Maybe they could make the application more native instead of using the botchy, almost-correct-but-not-quite Qt widget library.

And this is news how?
How could anyone not know this immediately?

Looks like it worked. They got them to post the PDF to wikileaks and now the site gets slashdotted.
Whether it's on the disc or downloadable, you're paying that money to license the software product.
I'm surprised that this could be news to anyone.
What, you say you didn't know that your Windows 7 disc has all five versions of Windows 7 on it, too?
You can't get blood out of stone. Pay your money or just don't play the game.
I didn't say they required security clearances, but they do require security clearance vetting. It's not the same thing.
RTFP, please.

The problem as I understand it is not just security but also denial-of-service related. Those attempts are consuming his server's resources.
